Yes, the EOS M’s AF is way slower than the EM-5′s AF. It’s a pity on an otherwise such well performing camera as the Canon EOS M. Tomek Kulas at M43.eu wanted to know how much slower than the EM-5. The video above shows a simple test: pointing both cams to the same subject and using touch-to-shoot.
Canon please give us a firmware update that fixes the issue!!
